A retrospective study was undertaken to analyse the risk factors for systemic emboli in infective endocarditis. Patients (n = 80; 70% males; mean age 65 years; range 20-91 years) with infective endocarditis, as defined by the Duke criteria and diagnosed using transoesophageal echocardiography during the period January 1995 to March 2001, were included. The average time between the start of the illness and the beginning of antibiotic treatment was 55 days (range 0-405 days). The pathogens identified were streptococci (n = 47), staphylococci (n = 11), enterococci (n = 9), and others (n = 4). In nine cases, blood cultures were sterile. Thirty patients with at least one embolic episode were compared with 50 control patients. According to univariate analysis, the main risk factor for systemic emboli was the size of the vegetation (12.4 mm vs. 7.8 mm; p = 0.0005). The risk of emboli was 57% when the vegetation measured > 10 mm and only 22% when it was < 10 mm (p = 0.003). The mobility of the vegetation was also a risk factor: 48% if the vegetation was mobile; and 9% if fixed (p = 0.003). Sex, age, pathogen, antibiotic treatment, type of valve and the number and position of the vegetations were not found to be risk factors. With multivariate analysis, only mobility was identified as a risk factor. Overall, mobile vegetations > 10 mm in size were associated with an increased risk of embolic episodes in infective endocarditis.
Background
It is unclear whether HIV infection affects the long‐term prognosis after an acute coronary syndrome (ACS). The objective of the current study was to compare rates of major adverse cardiac and cerebrovascular events after a first ACS between people living with HIV (PLHIV) and HIV‐uninfected (HIV−) patients, and to identify determinants of cardiovascular prognosis.
Methods and Results
Consecutive PLHIV and matched HIV− patients with a first episode of ACS were enrolled in 23 coronary intensive care units in France. Patients were matched for age, sex, and ACS type. The primary end point was major adverse cardiac and cerebrovascular events (cardiac death, recurrent ACS, recurrent coronary revascularization, and stroke) at 36‐month follow‐up. A total of 103 PLHIV and 195 HIV− patients (mean age, 49 years [SD, 9 years]; 94.0% men) were included. After a mean of 36.6 months (SD, 6.1 months) of follow‐up, the risk of major adverse cardiac and cerebrovascular events was not statistically significant between PLHIV and HIV− patients (17.8% and 15.1%,
P
=0.22; multivariable hazard ratio [HR], 1.60; 95% CI, 0.67–3.82 [
P
=0.29]). Recurrence of ACS was more frequent among PLHIV (multivariable HR, 6.31; 95% CI, 1.32–30.21 [
P
=0.02]). Stratified multivariable Cox models showed that HIV infection was the only independent predictor for ACS recurrence. PLHIV were less likely to stop smoking (47% versus 75%;
P
=0.01) and had smaller total cholesterol decreases (–22.3 versus –35.0 mg/dL;
P
=0.04).
Conclusions
Although the overall risk of major adverse cardiac and cerebrovascular events was not statistically significant between PLHIV and HIV− individuals, PLHIV had a higher rate of recurrent ACS.

We report a case of Schistosoma mansoni bilharziasis in a HIV patient 38 y after leaving an endemic region. A viable S. mansoni egg on a liver biopsy sample was diagnostic. Despite severe concomitant immunodeficiency the effective treatment was a single dose of praziquantel. Worms' intravascular longevity and the role of immunodeficiency as a possible factor in eggs retention after such prolonged latent schistosomiasis are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
